The design and establishment of the Polycystic Kidney Disease (PKD) Data Repository does not require, and may be constrained by, a narrowly conceived hypothesis. However, the PKD Repository has been designed to include demographic, clinical, biochemical, and genetic data that will further explore the natural history of the disorder and assess the factors that are likely to be associated with the progression of disease and the incidence of complications including renal failure, cardiovascular disease, and stroke.

Natural history of Autosomal Dominant Polycystic Kidney Disease (ADPKD) progression [ Time Frame: Up to 20 years ] [ Designated as safety issue: No ]

The primary interest of this protocol is to characterize the renal and extrarenal manifestations of ADPKD, evaluate the natural history of the disease progression, and explore potential associations between PKD gene variants and ADPKD phenotype.

Biospecimen Retention: Samples With DNA

Blood sample for genotyping of specific PKD1 and PKD2 mutations. Buccal and/or semen sample (optional and only if needed)

The goal of this project is to collect data from a large population of patients with PKD. Based upon the estimated prevalence of PKD (1:500 and 1:1000 live births), it is estimated that there may be 10,000 PKD patients in the New York City area. This sample size far exceeds any database established thus far. As many as 40% of affected PKD patients are reportedly unaware of a family history of this disease, in part because many patients may go undiagnosed until they present with a medical complication (e.g., hypertension, kidney failure). Furthermore, this initiative will provide an opportunity to compare data from racially diverse populations.

Eligibility

Ages Eligible for Study:

18 Years and older

Genders Eligible for Study:

Both

Accepts Healthy Volunteers:

No

Sampling Method:

Non-Probability Sample

Study Population

All patients enrolled in this study will have the diagnosis of autosomal dominant polycystic kidney disease (ADPKD). The diagnostic criteria for at-risk individuals (i.e., with a first degree family member with ADPKD) includes the presence of at least two (unilateral or bilateral) renal cysts, and two cysts in each kidney are considered sufficient for diagnosis in aged 15 to 29 years and in 30 to 59 years, respectively. In families of unknown genotype, the presence of one or more (unilateral or bilateral) renal cysts is sufficient for establishing the diagnosis in individuals aged 15 to 29 years, two or more cysts in each kidney is sufficient for individuals aged 30-49 years.

Criteria

Inclusion Criteria:

Males and females

Age 18 years and older

Previously diagnosed with ADPKD

Exclusion Criteria:

Inability to provide informed consent
